The story begins during the Revolutionary War, when Colonial schoolteacher Justin Morgan (Don Murray), though nearly penniless, sets about to develop a sire for horse-racing purposes. Not one but two exciting races cap this recreation of a little-known historical event. Featured in the cast are Lana Wood, R. G. Armstrong and Gary Crosby. Based on the book by Marguerite Henry, Justin Morgan Had a Horse was originally telecast February 6 and 13, 1972, as a two-part installment of The Wonderful World of Disney.
